High Quality Single Speed Bicycle Chain for Adult Bike

In the transmission device of machine tool, the commonly used transmission parts include pulley, gear, worm turbine, gear rack and screw nut, etc. Through these transmission parts, the power source and the actuator, or the two actuators are connected, which is called the transmission connection. A series of sequentially arranged transmission parts that constitute a transmission link are called transmission chains.

The roller is looped on the sleeve. When working, the roller rolls along the sprocket tooth profile, which can reduce the wear of the gear teeth. The main wear of the chain occurs on the contact surface of the pin shaft and sleeve. Therefore, there should be a little gap between the inner and outer chain plates so that the lubricating oil can penetrate between the friction surfaces. The chain plate is generally made into an "8" shape, so that its cross sections have nearly equal tensile strength, and also reduce the mass of the chain and the inertia force during movement.
